The quantum Hall effect (QHE) is traditionally considered to be a purely two-dimensional (2D) phenomenon. Recently, however, a three-dimensional (3D) version of the QHE was reported in the Dirac semimetal ZrTe5. It was proposed to arise from a magnetic-field-driven Fermi surface instability...
Atomistic simulations of chemical, biological and materials systems have become increasingly precise and predictive owing to the development of accurate and efficient techniques that describe the quantum mechanical behaviour of electrons. Nevertheless, t
Getting something from nothing is the dream of perpetual machine enthusiasts. Have we finally cracked the code? Read on to learn about quantum vacuum physics.
On forward biasing, the bn junction showed a step-like behavior, which could be a direct demonstration of the quantum size effects (QSE) exhibited by these clusters. This effect can be assigned either to the enhancement of the collective Coulomb blockade phenomenon occurring in the quantum dots ...
* OSA Quantum 2.0 Conference website Given what we now know (collectively), what should we do next? These forward looking statements are the personal opinions of the speaker. They are not to be construed as the official position of Google. There were reasons to be optimistic in 2015 Andrea...
As the field further expands, the various quantum (whorls) begin to separate and the interaction with its neighbors becomes less distinct. Each quantum continues to have the same energy but its neighbors contribute less and less to its effect when exposed to a detector, unless lenses or antennas...
nanomaterials have gained enormous attention for their value in improving biosensor performance owing to their high surface-to-volume ratio and quantum size effects. This article reviews the impact of nanotechnology on the design, development, and performance of sensors for the detection of viruses. Sp...
